IMPROVEMENT IN DUNl-PING-SCRAPERS.V

Specification forming part of Letters Patent No. 14,l7, dated May G,1856.

To a/Z whom, t may concern.-

Be it known that I, MATHEW S. KAHLE, of Lexington, in the county ofRockbridge and State of Virginia, have invented certain new and usefulImprovements in Dumping-Scrapers; and I do hereby declare the following'to be a full, clear, and exact description of the construction andoperation of the same, reference being had to the accompanying drawings,in which- Figure l represents a top plan of the scraper. Fig. 2represents a longitudinal section through the machine as it stands whenloaded, and representing in red lines its position when about to receiveits load. Fig. 3 represents a vertical section through machine in itsposition after it is dumped.

Similar letters where they occur in the severa-l figures denote likeparts.

To enable others skilled in the art to make and use my invent-ion, Iwill proceed to describe the same'with reference to the drawings.

A B represent a pair of carrying-wheels, united by a bent axle C, towhich the scraper D is firmly affixed, so that said axle shallconstitute the turning shaft of the scraper. The scraper D is shed witha circular piece of iron or steel E, and its body should be large enoughto contain about an ordinary cart-load of earth.

F F are the handles of the scraper, which should be removable, so thatthe body of the scraper may turn around to dump and continue to turn toright itself again without inconvenience.

The scraper is so hung on the axle that it may turn clear around in afull circle or vibrate half around and then back again, as will behereinafter described in the operation.

G G are the shafts, united at their rear to the axle C and braced infront of the scraper by the cross-bars II I. On the bar I-I is pivoted alever a, to one end of which is connected a rod l), ruiming back so asto be conveniently reached by the operator. To its other end is attacheda forked arm c, to each fork of which is pivoted a connecting-bar d,which bars d are in turn united to the front ends of two rods e e,pivoted, respectively, to the shafts G G at F F. The rear ends of therods c c are bent around to form hooks, and when drawn together bypulling back the rod b these bent ends or hooks enter holes or recessesin the blocks g g on each side of the body of the scraper, and thus holdit Alirinl y to prevent its swinging on the axle.

The red lines in Fig. I show the position of the above several deviceswhen the catches are thrown out, to either allow the scraper to receiveor discharge its load of earth.

The operation of the machine is as follows: rlhe handles beingintroduced into their staples and the rod b pushed forward to throw outthe catches, the scraper is raised up behind, as seen in red lines inFig. 2, until it fills with earth. It is then brought down, the rod l)pulled back to throw in the catches, and the body is locked in theposit-ion shown iu black lines, Fig. The handles may nowbe taken out andused for the next machine in Iits turn, and the machineA drawn away towhere the earth is to be deposited. Then arrived at the proper place,without stopping the machine the rod b is pushed forward to release thecatches, the front of the scraper drops and catches against the ground,while the machine, still moving on, pulls over the body D, the axle Cturning in its wheels to admit of this. The machine continuing to moveon,the rear of the body is thrown down, and, catching against theground, turns it around aga-in in proper position, and so on.

Having thus fully described the nature of my invention, what I claim'therein as new, and desire to secure by Let-ters Patent, is-

So attaching the body of the scraper pernn'tnently to a bent axlesupported in a pair of wheels as that said body may be dumped andreturned back to its original position and ready for the next loadwithout stopping the horses or changing their direction, substantiallyas herein set forth.
